I am a focal fan and have a larger passive version of the CMS line (which I love for mixing) and the SM9s which have the same tweeter and maybe mid driver as the Solo/Twin line. Anyway, the way I understand it is the Twins have a bigger low end which I'm sure would help in your space if you're working on low-end-critical music styles. So the key question is how much bass do you need to throw out into the room to work effectively. If more, then maybe the Twins. If less, then maybe the Solos.
